SYLVANUS HEMINGWAY, OF NORWICH, NEW YORK.

RAILROAD-BED.

Specification of Letters Patent.

Patented Dec. 18, 191 7.

Application led March 15, 1917. Serial No. 155,037.

To all whom t may concern.'

Be it known that I, SYLvANUs HEMING- WAY, a citizen of the United States, residing at Norwich, in the county of Chenango and State of New York, have invented certain useful Improvements in Railroad-Beds, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to improvements in railroad beds and as the primary aim and object it is contemplated to provide a railroad bed the body of which is formed of cementitious material, novel means being provided for reinforcing the bed and being adapted to be molded into the bed whereby to increase the rigidity and longevity of the bed when in use.

It is an equally important object of the present invention to anchor track fastening means in the body when it is molded so as to consequently permit of rails being rigidly fastened to the upper surface of the body.

More particularly, the present invention embraces an improved construction for shedding water to consequently prevent weakening of the body.

It is a more specific object of the present invention to form the upper surface of the body of such material that will prevent water from saturating the body, thus maintaining the bed or body dry and firm at all times and to also provide cooperative means for effectively maintaining the rails in a proper position on the curved surface of the body.

Among the other aims and objects of the present invention may be recited the provision of a device of the character mentioned with a view to compactness, and in which the parts are few, the construction simple, the cost of production low and the efficiency high.

Other objects as well as the nature, characteristic features, and scope of this invention will be more readily apparent from the following description taken in connection with the accompanying drawings and pointed out in the claim, forming a part of this specication.

The invention is clearly illustrated in the accompanying drawings in which Figure 1 is a perspective of one form.

Fig. 2 is an enlarged transverse section thereof.

Fig. 3 is a transverse section of another form o-f the invention and Fig. L is another' transverse section of the form shown in Fig. 3.

Similar characters of reference are proyided in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings I provide. a track bed including a body 1 formed of concrete, the upper portion 2 of the body being formed of asphalt or similar cementitious material to prevent rain water from weakening the body while the upper surface of the body is curved transversely and conveXly as at 3 1n oider to shed rain water and coperate with the asphalt so as to permit of the body being maintained dry and firm at all times.

l/Vith a view toward providing suitable means for reinforcing the body I employ a plurality of bars a formed of any suitable metal and anchor these bars transversely of the body when the body is molded, the bars being` positioned approximately intermediate the height of the body.

For the purpose of providing improved means for securely fastening the rails 5 to the upper surface of the head of the body 1 have anchored the heads 6 of the fastening bolts 7 in the body, the free ends of the bolts projecting above the upper surface of the body and through blocks 8 and to the sides of the base flanges of the rails 5, supported on the blocks and held in a rigid position by means of the ianges 8 projecting from the nuts 9 the latter being arranged in threaded engagement with the bolts. The blocks S have their-under surfaces curved as at 10 to conform to the curvature of the upper` surfaces of the body while the outer ends are thickened so as to arrange the upper surfaces in the same horizontal plane to consequently effectively maintain the rails 5 in a proper position.

In the form of the invention illustrated in Figs. 3 and 4, the body 11 is constructed similarly to the body 1 and likewise is reinforced by bars 12 similar to the bars 4. Instead of employing the fastening bolts 6 however headed spikes 13 are employed to pass by the sides of the base anges of the rails 14 through the blocks 15 similar in construction to the blocks S being finally disposed in corresponding openings 16 formed in the body when it is molded so that the heads of the spikes clamp the base flanges of the rails. If desired Cross bars l? formed of bendable material may be employed7 the main portion of the bars being constructed to conform to the upper surface of the body intermediate the rails 11i while theii outer ends are bent to provide rail base engaging flanges 18 as illustrated in Fig. 4e to reduce the possibility of spreading of the rails to a minimum.

In view of the foregoing description it is thought that a further description regarding the operation of the invention is unneces sary. Likewise7 it is believed that the advantages of the invention when in use will be readily apparent because by the present construction it is unnecessary to employ wood cross ties and additional supports for the rail joints as is necessary in the Construction of the track beds now in use. In addition it will not be necessary t0 employ a large number of track walkers for the reason that there is less danger of the track bed becoming` damaged by cinders7 the action of the weather, etc.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts .may

be made within the scope of the appended claim and without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent, is

A railroad bed construction including a body formed of concrete and having the upper portion formed of asphalt the upper surface of the body being curved transversely and conveXly7 reinforcing blocks of metal molded transversely through the body, fastening bolts the heads of rwhich are anchored in the body when the body is molded, the upper ends of the bolts projecting above the upper surface of the body, rail supporting blocks triangular in cross section having their under surfaces curved and resting on the upper surface of the body,v said blocks being engaged and maintainediby the upper projecting ends of the bolts, a pair of rails mounted on the body and seated on the blocks,V rail flange engaging washers disposed about the bolts and engagingthe base tianges of the rails, nuts for clamping the washers and consequently the rails in position, cross bars curved longitudinally and restingtransversely on the upper surface of the body, and rail base engaging flanges formed on the ends of the cross bars.

In testimony whereof I affix my signature.
